A truck has been making its way around Middlesbrough in the the hope of shaming two brothers who tortured their pet dog and filmed it.

Andrew Frankish, 22, and brother Daniel, 19, originally from Redcar, sparked outrage when horrific footage of an attack on their pet dog, Baby emerged.

After both received suspended sentences various petitions were created in the hope of getting the duo re-sentenced.

Pressure group, Operation Frankish, was set up specifically to draw attention to the brothers and their latest stunt “Operation Tour De Frankish” saw a 30-foot van drive around the town centre with the message “JAIL THE FRANKISH BROTHERS.”

The billboard on the van, which drove around the town from 9am until 5pm today, was designed to look like a Google search engine and said: “The Frankish Brothers Walked Free From Court Keep Britain Safe Jail The Frankish Brothers.”

It also urged passers by to “Google The Frankish Brothers.”

The group also claims to be responsible for the aerial display during Middlesbrough FC’s clash with Ipswich when a plane flew over the Riverside Stadium with a banner that also read: “JAIL THE FRANKISH BROTHERS”.

The group posted a message on their website yesterday and said they would “storm Middlesbrough” with the aim of creating the maximum amount of exposure in the hope of the pair receiving a harsher sentence.

The brothers were fined and banned from keeping animals for life after admitting animal cruelty following an RSPCA prosecution, but dodged jail - a decision that sparked widespread controversy.

The truck, which was crowdfunded, made its way across the town and drove through areas that would be deemed the busiest before parking up outside the Cleveland Centre.

Speaking of the response to the stunt, a spokesperson from Operation Frankish, said: “The ones (public) we’ve heard from so far all love it. We often get the best response from locals because they’re so disgusted that the abuse happened right on their doorstep.

“When choosing the message we thought about it from the perspective of someone who is completely unaware of the story.”

More than 447,000 people have now signed a change.org petition calling for the brothers to be imprisoned with a further 362,700 backing a separate ‘Justice for Baby the Bulldog’ campaign on the petitionsite.com asking for a tougher sentence, taking the total above 809,000.

Asked whether this would be the last of their stunts, the spokesperson, added: “On the contrary. These are just the starter - not the main course.
